Merge branch 'tests-init'

Fix parallel testsuite run with Zsh.

This change deals with a Zsh incompatibility in the handling
of the special shell variable `$0' in sourced files; this
incompatibility used to cause utter breakage when the
Automake testsuite was run in parallel mode with Zsh as
the $(TEST_LOG_COMPILER).

For more information, please refer to the thread "Fix parallel
testsuite run with zsh" on automake-patches, dated 2010-12-22:
 <http://lists.gnu.org/archive/html/automake-patches/2010-12/msg00135.html>

This change works around the problems described above for Zsh 4.3
or later, and offers better error messages (instead of random
failures) for earlier Zsh version.

* tests/README (Supported shells): When describing the manual
workaround about the Zsh incompatibility in the handling of `$0',
tell that it is now needed only with Zsh versions preceding 4.3.
Done also some minor rewordings.
* tests/defs-static.in ($argv0): New variable, offers a workaround
for the Zsh incompatibility in the handling of `$0'.
Abort if that variable cannot be correctly set (can happen only
in older Zsh version).
* tests/defs ($me): Define using `$argv0', not `$0'.

Tests defs: keep track of original $AUTOMAKE and $ACLOCAL values.

This is especially useful for tests which might want to run
automake and aclocal without additional flags and warnings.

* tests/defs-static.in ($original_ACLOCAL): New variable.
($original_AUTOMAKE): Likewise.
* tests/help.test: Use them.
* tests/help2.test: Likewise.
* tests/help3.test: Likewise.
* tests/help4.test: Likewise.

docs: cygnus mode doesn't require AM_CYGWIN32 macro.

running "make -k" one single time and grepping its output for

Merge branch 'tests-dejagnu-extend'

Extend and improve tests on DejaGnu support.

* tests/dejagnu.test: Do not create useless dummy test script.
Add trailing `:' command.  In heading comments, add reference
to ...
* tests/check12.test: ... this new "semantic" test, covering
concurrent use of dejagnu tests, simple tests and `check-local'
target.
* tests/dejagnu2.test: Make test more reliable, by avoid weak
grepping of make output.  Prefer `cat' over `echo' to append
to configure.in.  Quote literal dots in grep regexps.  Prefer
`grep -c ...' over `grep ... | wc -l'.  Make grepping of
automake stderr slightly stricter.  Add trailing `:' command.
* tests/dejagnu3.test: Prefer `cat' over `echo' to append to
configure.in.  Check stderr of expected-to-fail "make" call.
Remove extra blank lines from Makefile.am.
* tests/dejagnu4.test: Prefer `cat' over `echo' to append to
configure.in.  Prefer `mv -f' over plain `mv' when the target
file already exists.  Avoid extra mkdir calls by creating more
directories at once.  Better use of blank lines.  Check that
the `*.log' and `*.sum' files are created by runtest also when
"make check" fails.
* tests/dejagnu7.test: Prefer `cat' over `echo' to append to
configure.in.  Better use of blank lines.  Add a trailing `:'
command.
* tests/dejagnu6.test: Likewise, and give the dejagnu test a
more descriptive name.
* tests/dejagnu5.test: Likewise.  Also, simply define package
name to `$me' rather than using a non-obvious sed script to
extract it from `AC_INIT', and write the Makefile.am with only
one command.
* tests/Makefile.am (TESTS): Updated.

Avoid running installed automake from 'libtool --help'.

* tests/subobj9.test: Export AUTOCONF and AUTOMAKE.
Together with fixed Libtool, this fixes check-coverage to not
invoke installed automake.

Extend tests on AC_LIBOBJ and friends.

* tests/aclibobj.test: Removed, superseded by ...

longer filenames to be grepped.
* tests/libobj8.test: Enable `errexit' shell flag, and related
changes.  Add trailing `:' command.  Use the configure.in
stub provided by ./defs, rather than writing it from scratch.
* tests/libobj2.test: Likewise.  Also, add calls to autoconf,
./configure and make, to ensure everything really works.

stricter.  Add trailing `:' command.

Fix typo in ChangeLog

Merge branch 'maint'

Fix spurious silent*.test failures for $CC != gcc

In some tests on automake-produced silent rules, we forced the
use of gcc depmode to improve testsuite coverage; but this has
unsurprisingly led to spurious failures when some non-GNU C
compilers were used.  So we are now careful to require GCC in
tests that force gcc depmode.

From reports by Ralf Wildenhues.

* silent5.test: Test removed, its content split into ...
* silent-many-generic.test, silent-many-gcc.test: ... these new
sister tests, the latter of which forces gcc depmode and lists
"gcc" in $required.
* silentlex.test: Test removed, its content split into ...
* silent-lex-generic.test, silent-lex-gcc.test: ... these new
sister tests, the latter of which forces gcc depmode and lists
"gcc" in $required.
* silentyacc.test: Test removed, its content split into ...
* silent-yacc-generic.test, silent-yacc-gcc.test: ... these new
sister tests, the latter of which forces gcc depmode and lists
"gcc" in $required.
* tests/Makefile.am (TESTS): Updated.

Modernize, improve and/or tweak some test scripts.

* tests/maintclean.test: Use proper m4 quoting.  Add trailing `:'
command.
* tests/sinclude.test: Likewise, and add a couple of blank lines,
for clarity.
* tests/make.test: Move setting of `errexit' shell flag earlier in
the script (just after inclusion of ./defs).  Use the configure.in
stub created by ./defs, rather than writing it from scratch.  Some
cosmetic changes in spacing.  Ensure we wait enough time before
touching configure.in to trigger the rebuild rules.
* tests/makej.test: Use `$me' instead of hard-coding the test
name.  Add trailing `:' command.
* tests/version7.test: Likewise.
* tests/space.test: Enable `errexit' shell flag, and related
changes.
* tests/makevars.test: Likewise.  Also, prefer trailing `:' over
trailing `Exit 0', and be more tolerant of white spaces when
grepping Makefile.in.

Fix some typos in ChangeLog

Separate checks on target overriding into multiple test scripts.

* tests/overrid.test: Deleted, its contents separated into ...

* tests/override-html.test: ... and this new test ...
* tests/override-conditional-1.test: ... and this new test ...

xfailing).
* tests/Makefile.am (TESTS, XFAIL_TESTS): Updated.
